[Changes, induced by certain flavonoids, of the hypotensive effects of arachidonic acid]
Abstract:
In the rat, silybine and Z 12007, a derivative of rutoside, increase the vasodepressive activities of arachidonic acid, a prostaglandin precursor. They reduce the activity of PGE2. Quercetine also increases the hypotensive action of arachidonic acid. These three flavonoids are supposed to increase the prostaglandin biosynthesis.
